Description

A kind of reversing wire device

Technical field

The utility model relates to a kind of reversing automobile auxiliary device, relates in particular to auxiliary the assisting with guide wire of a kind of video and is the reverse aid of one.

Background technology

The develop rapidly of Domestic Automotive Industry has been injected great vitality to Automobile Electronic Industry, and the development of automobile video vehicle back radar reverse image, the visual product of reversing is also day with a thousand li.At present, reversing gear is mainly taked ultrasonic ranging and backsight shooting, and the two respectively has excellent lacking, the former definitely judging distance, but the things that has a lot of super sonics to sense brings potential safety hazard to reversing, the back view picture is directly perceived, all is some shortcoming of accurate assurance of adjusting the distance.

Vehicle-mounted audio/video device is alleviated the long-duration driving fatigue of chaufeur, be widely used, but in the prior art, vehicle-mounted audio/video device and reverse image all is installed separately, and has increased the unnecessary consumer cost of user.Notification number is that the Chinese patent of CN20122310Y discloses a kind of visual backing system device that has video playback capability, this device is by realizing visual reversing and the combination of video (multimedia) playing system in a Circuits System, by the mode switch button, can between reversing mode and visual-audio mode, switch easily, and make up with back mirror, not only dwindle the volume of system, also greatly reduced the cost of system.But there is certain potential safety hazard in the accurate assurance problem that the still unresolved backsight shooting of this patent is adjusted the distance.

In the prior art, also some combines with guide wire by the backsight shooting, user's backing distance there has been assurance comparatively accurately, but a problem also can occur: guide wire only be responsible for to guide user's parking a little of appointment of moveing backward, if in the garage, guide wire can call user's attention yet luggage boot after the reversing whether can open, withdraw baggage to the user and brought inconvenience.

The utility model content

The purpose of this utility model provides a kind of reversing wire device, this device: 1, be installed together with vehicle-mounted audio/video device, dwindled the volume of device, also greatly reduce cost; 2, the backsight shooting combines with guide wire, the true directly perceived and accurately judging distance of image; 3, guide wire is set to 4, guide wire can be adjusted by the user to the distance of nerf bar, remind the user relievedly to move backward for farthest one, reminding customer requirement to slow down for far away one goes slowly, remind the user to the minor increment of this distance for nearer one for extraction boot luggage, remind the user should not stop working convenient and swift hommization again, intellectuality for nearest one continuing reversing.

The purpose of this utility model is achieved through the following technical solutions:

A kind of reversing wire device comprises camera, video decode multichannel selection conversion D/A, shows control, DRAM, FLASH, navigation CPU, velocity pulse, read-out.Camera collection to information select conversion D/A on the one hand via show that the control back shows in read-out by the video decode multichannel, deliver to navigation CPU on the other hand, navigation CPU comprehensive described camera collection to the parameter information that is provided with of information and the guide wire that is stored in FLASH, show by read-out, velocity pulse is connected to navigation CPU, is used to judge the speed of a motor vehicle.

As improvement, read-out adopts 7.0 cun touch TFT read-outs, include in the read-out 7 removable, generate the point of guide wire automatically.In read-out, the point that color is identical is combined into a guide wire, and the user can select the distance of guide wire and Federal bumper according to the reversing custom of oneself, only needs the position of 7 points in the moving display screen to get final product during selection.Preferably, guide wire is 4, is followed successively by first guide wire, second guide wire, the 3rd guide wire and the 4th guide wire from the distance of distance bumper/spoiler.

Preferably, navigation CPU adopts little process chip, can be singlechip chip.

Preferably, camera and video decode multichannel selection conversion D/A's is to realize by composite video broadcast singal (CVBS) alternately.

What preferably, the video decode multichannel was selected to change D/A and navigated CPU is to realize by the RGB565 form alternately.

The utility model compared with prior art has following advantage:

1, is installed together with vehicle-mounted audio/video device, dwindled the volume of device, also greatly reduce cost.

2, the backsight shooting combines with guide wire, the true directly perceived and accurately judging distance of image.

3, guide wire is set to 4, guide wire can be adjusted by the user to the distance of nerf bar, first guide wire indication user can relievedly move backward, second guide wire indication customer requirement slows down and goes slowly, the 3rd guide wire indication user is to the minor increment of this distance for extraction boot luggage, the 4th guide wire indication user can not should stop working convenient, fast hommization again, intellectuality continuing reversing.
